Abstract

PURPOSE:To increase the transmission efficiency by securing a collective transmission for the erroneous block and the subsequent block at the transmission side and in accordance with the reception error signal. CONSTITUTION:First, block B1, B2, B3, B4 and B5 are transmitted en bloc, and presence or absence of error is detected for the transmitted blocks at the reception side. Then error signal NAC (2, 5) are sent back for erroneous block B2 and B5. Block B2, B5, B6, B7 and B8 are transmitted en bloc at the transmission side, and the error check is given to these blocks at the reception side. When the error is detected with blcok B5 and B7, block B5, B7, B9, B10 and B11 are transmitted at the transmission side based on error signal NAC (5, 7). Then if no error is detected, reception confirmation signal ACK is sent back. And subsequent block B12, B13, B14, B15 and B16 are transmitted en bloc at the transmission side.
